Abstract (en)

[origin: EP1953412A2] There is provided a pretension loading method for a power transmission chain, the method including the steps of: (a) maintaining the chain in a substantial tension state without a slack by controlling tension of at least one of the plurality of rollers while endlessly rotating the chain; (b) measuring a length of the chain in the tension state; (c) stretching the chain to a target length by controlling a displacement of the at least one of the rollers; (d) maintaining the chain in a substantial tension state without a slack by controlling tension of the at least one of the rollers; and (e) measuring the length of the chain in the tension state. At this time, the steps (c) to (e) are repeated until a difference between the target length and the length of the chain which is measured in the step (e) is less than a predetermined value.
